How many different types of atoms are in the formula Ba(OH)2 • 8H2O?

1 answer:

6 0

The answer should be A.

Why?
“Different type of atoms” which refers to different element present in the compound. Only Barium, Oxygen, and Hydrogen found in that compound, thus there are 3 types of atom founded it hydrated barium hydroxide.

I hope this enlighten. Apologize for any English or Chemistry concepts.

Nitrogen dioxide reacts with carbon monoxide to produce nitrogen monoxide and carbon dioxide. NO2(g) + CO(g) ⟶ NO(g) + CO2(g) A

Naya [18.7K]

Answer: The rate law for the reaction is $\text{Rate}=k[NO_3][CO]$

Explanation:

Rate law is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.

In a mechanism of the reaction, the slow step in the mechanism determines the rate of the reaction.

For the given chemical reaction:

$NO_2(g)+CO(g)\rightarrow NO(g)+CO_2(g)$

The intermediate reaction of the mechanism follows:

Step 1: $2NO_2(g)\rightleftharpoons NO_3(g)+NO(g);\text{ (fast)}$

Step 2: $NO_3(g)+CO(g)\rightarrow NO_2(g)+CO_2(g);\text{(slow)}$

As, step 2 is the slow step. It is the rate determining step

Rate law for the reaction follows:

$\text{Rate}=k[NO_3][CO]$

Hence, the rate law for the reaction is written above.
